Facebook Autolike script

I need a facebook script autolike script. I need the visitors (if the visitor is logged in to facebook currently) to autolike my website when they visit my dot com website. This should happen without the user interaction, and without any popups/messages that could warn the user about what is happening. The autolike function should take place as soon as the page loads. I'm looking for a non-iframe facebook autolike script. I already have several facebook autolike scripts that use the iframe method. It works when the visitor on my dot com website clicks on something and it autolikes my facebook fan page if that visitor is currently logged into facebook. Lately I've seen websites that are using a new autolike script that doesn't require the visitor to click on anything to get the autolike to work. The autolike function takes place as soon as the page loads. This is the script I'm looking for.
